Abstract

The inventional relates to a synchronous semiconductor memory integrated circuit comprising a plurality of memory blocks including a plurality or memory cells for storing information; an input for receiving an external clock input;
   an address input means, and an output means for sequentially outputting a plurality of data which belong to separately addressable locations in said memory blocks at substantially the same interval, said plurality of data including data stored at a location in said memory blocks corresponding to a first address and a second address provided by said address input means.
Furthermore, the invention relates to a method for accessing such a memory and a system comprising such a memory.
